I've continued to use the old (circa 1989) Reese dual cam WDH with sway control. In fact, I set the chains to the same links on each side with the F250 as I did on the F150.
My camper weighs the same as it always has, as does the tongue. The F250 has a lot more capacity than the F150 did, but I'm only using a fraction of that capacity. By setting the bars the same, I'm still distributing the same weight I always have between the front and rear axles.
While the F250 has electronic sway control built in, I prefer not to engage it, and allow the mechanical sway control of the WDH to handle it. Keeping in mind that I have never experienced any problems with sway, I suppose if it got bad enough that the mechanical couldn't handle it, the truck's on board control would take over.
I would definately stay with the Reese Dual Cam as it works to resist the tendency for sway
and the cams work to return from any offset or sway. This is not present in the Equalizer hitch that simply resists sway and also resists a return from sway.
